Excellent. I should have realized that I would be able to disable the
genesys backend initially and given that a try. Obviously I should have
realized that even after reviewing the
https://gitlab.com/sane-project/frontends/-/issues/22 and
https://gitlab.com/sane-project/backends/-/issues/464.

I commented out the genesys backend.

  $ scanadf -L
device `brother4:net1;dev0' is a Brother MFC-J485DW MFC-J485DW
device `airscan:e0:Brother MFC-J485DW' is a eSCL Brother MFC-J485DW
ip=192.168.1.28

  $ scanadf -V
scanadf (sane-frontends) 1.0.14

1. Would this issue have caused the adf to completely fail to be
functional through SANE?

I would like to start a new thread concerning the adf on my Brother
MFC-J485DW (Xsane is only displaying a preview for 1 of the 3 pages I am
trying to scan with the adf feature).

Thank you for the excellent help. I would like to let you know for some
time I was using an Outlook email account and I could never receive
messages from the sane-devel list and I did not know why since the
Outlook email client confirmed the emails had been sent.
